China's QJMOTOR small-displacement supersport, the 'SRK 450 RR,' is drawing attention in South Africa. Its 421cc inline-four produces 76hp at 14,000rpm and comes equipped with Brembo radial calipers, fully adjustable Marzocchi suspension and a 7-inch TFT display. Priced at around R104,995, it reportedly reaches a top speed of over 230km/h.

An inline-four spinning to 14,000rpm making 76 horsepower, top speed over 230km/h? My fingertips are itching. Launch control, a setting that lets you disable rear-only ABS, clip-ons and rear-set pegs - it's built with full intent to attack from corner entry all the way to exit. That high-pitched scream of a small-displacement multi-cylinder is something you can't get from a 250. This is a bike I want to rev out for myself trackside.

104,995 rand, how much is that in yen? Feels surprisingly reasonable actually.

Loaded equipment's nice, but how durable is QJMotor's inline-4 actually?

With Brembo and Marzocchi at this price, it's a rival to the ZX-4RR.

The small-displacement inline-4 supersport is really coming back? I want one.

A 421cc inline-4 revving to 14,000rpm for 76hp is pure romance.

Small-displacement inline-4s bring back memories of the old CBR400RR and ZXR250.

Is an inline-4 revving all the way to 14,000rpm really that impressive?
